Most manufacturers seem to have abandoned trying to support them, their community has slowly disappeared, and you can see it.
They seem to only care about Espressif these days.
Zephyr support has not been updated in ages (2021)
Patches submitted to platformio arduino to add Giga R1 support have gone unreviewed for years (I get poked every so often because i did some work on it, so i see the github comments).
The only things that seem to be in okay shape these days are ESP and STM32.
Given the other options at this point, it is nowhere near as useful as it used to be.
That is partially on PlatformIO. AFAIK, they started pushing hard the scheme "be a partner (meaning pay us) or we won't even accept external contributions to support your platform".
ESP had a pretty public dispute with them (payment wasn't explicitly mentioned but can be inferred).
