Could you please attach an example addon that can be used to reproduce this? 🙂
Since at least 1.21.50 (based on the duplicate reports, and presumably since MCPE-131325 got fixed), this is also reproducible with regular rain and is no longer limited to solely thunderstorms. The circumstances for reproducing this with rain are identical to those of thunder, the only difference being that, from my testing, you need to leave and rejoin the world for the desync to occur.

This is intentional, see MCPE-59494
Are you able to check whether MCPE-167346 may be the cause behind this? Frogs may fall through blocks and suffocate in them if there are any doors, partial/non-full blocks, or an air block beneath any block.
This is intentional behavior, see MC-328

The issue with flint and steel losing durability while breaking blocks is being tracked at MCPE-61176
Keep in mind that sweet berries also spawn naturally in cold biomes where it snows, yet cannot be snowlogged. But alas, as you stated, it's up to Mojang to decide how to go about resolving the issue 🙂

Can confirm, however, this is most likely intentional, as this behavior would be consistent with other similar vegetation such as dead bushes (see MCPE-171701).
Can confirm. No idea why I wasn't able to reproduce this initially.
Are you able to attach a screenshot/video of this?
Can confirm.
Can confirm, affects 1.21.70.20.
