Migrated block on home page shows 'This block is broken or missing.'

When I migrate the site now, I get:

This block is broken or missing. You may be missing content or you might need to enable the original module.

For the front page block-whatido block. I'm guessing that the configuration has a UUID that is installed when the site is installed, but the migration creates a different block UUID when I run the migration, and the configuration is referencing a block that doesn't exist.

I seem to remember running into this same issue in the past before :(

Heh, now I remember. There's a whole bunch of semi-related issues here:

• "This block is broken or missing..." should only be shown to users that have access to do something about it
• #2906919: Allow users to create a block content entity with a specific UUID if it is a missing dependency of a config object
• #2756331: Custom blocks cannot be properly exported and imported

There's even a module to help with this problem (Recreate Block Content), but that's yet-another-module-to-fix-one-tiny-thing that I don't want to have to rely on.

I might add some sort of hook that connects the migrated block to that instance with the different UUID in code, maybe? Or make this another 'manual step after completing the migration' :/

I'm going to just stick with #55 — manually recreating the blocks on reinstall. If this were a much greater effort over a longer period of time I'd figure out a way to get it to work out of the box, but since I want to get this thing launched... I'll just go ahead and do it manually.
