Previously tags to update branches occurred within hours of each other and 19.07 was introduced with 18.06.3. Any insights on 20.x release and if 4/32 devices will be abandoned or accommodated?
19.07 will be the last release with support for 4/32 MB devices

Sorry, I should have linked this in my original post
OpenWrt-devel May 2020 thread: Skinny platforms
It looked like "Skinny Platforms" were being reconsidered but I was not aware of any code being submitted to that end.
I'm no developer, but I don't see this happen anytime soon.
In the context of the "Skinny platforms" discussion, you could ask your question
on the mailing list.
As an indication, I've seen a few devices getting disabled in master in the past few months on ath79/tiny and other similarly constrained platforms. Heck, I even had to fight with a device with more flash to get the kernel to build for it.
I don't think developers are reconsidering their 4/32 stance, frankly.
