Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

If only I wanted more ABS sets though. GMK, please somehow design a new process to make similar caps in PBT.
Excluding aesthetics, the most important characteristics are thickness, texture, legend type, then material.
PBT is not noticeably more "durable". It is "harder" than ABS, but this makes it brittle as well. EnjoyPBT/Gateron had a number of instances where their PBT in Cherry profile cracked and broke without applying ludicrous amounts of force in keycap removal. PBT does not resist getting oily buildup; your fingers do not magically produce less oils/sweat on PBT. I still have to wash my EnjoyPBT sets once in a while if I use them extensively for gaming, as the buildup on WASD becomes very noticeable and undesirable, even on such a PBT keyset where the keys are smooth to begin with.
I don't understand how Cherry caps "amplify scratchiness sound of MX switches". Looks like your switches need some lubing or you just need a better switch, because I have GMK and EnjoyPBT on the same board and this is not the case, even with stock "new" Blacks (pretty much the epitome of "scratchiness" on stock Cherry MX). 1.5mm PBT from EnjoyPBT/BSP/IMSTO are already Cherry caps, just like 1.5mm GMK...your point is? Majority of respected 1.5mm PBT sets are in either Cherry or StepScupture 2, so why the distinction between 1.5mm PBT and 1.5mm Cherry?
Yellowing can be conveniently reversed through the retr0bright process, and even considering that ABS does yellow over time, it takes many years before it is apparent. The only HHKBs whose cases have turned yellow are the original HHKB Professional 1 models, which have been around for more than 10 years. My PS/2 G80-3700 was made in early 2000 and was used on-off since then; no sign of yellowing on either the OG Cherry doubleshots or the case.
Point being: you stick to what you like, which apparently is PBT (nothing wrong with that), but do so without feeding misinformation about ABS and fuelling the PBT circlejerk. Cherry's original ABS Doubleshots found on old G80 boards, as well as GMK sets, are just as valuable as original Cherry dyesubs.
