The main difference between firmwares 5.11.* and 5.12 (and above) is an ability to block firmware ota updates: simple blocking directory vs renaming sys fles.
If a user has upgraded over 5.12 - there are no reasons not to upgrade to 5.13.3.

So it might be enough to have just two magic images: for 5.11.2 (the last 5.11.*) and for 5.13.3 (the last jailbreakable) for all models starting from PW3 and newer (except PW4).
No need for PW4 images at all (well, not urgent).

The latest update for PW2 and KT2 is 5.12.2.1.1, highly likely with closed vulneability, need to be tested. 5.12.2 is good for sure.
