Undocumented Gem Incompatibilities with Rails 7.1
For example, take the popular data-migrate gem. Its gemspec requires activerecord >= 6.1 with no upper bound. Looking at the changelog, though, you'll see that support for Rails 7.1 wasn't added until version 9.2.0. Older versions will hit this exception when someone tries to run migrations under the latest Rails, even though bundler installs the package with no warning.

Changing Tires at 100mph: A Guide to Zero Downtime Migrations
At least for Rails there are several gems available (ie https://github.com/WeTransfer/ghost_adapter or https://github.com/departurerb/departure) that seamlessly hook into the existing migration system and will run all eligible migrations through gh-ost or pt-osc as needed. You're right that it's not free but it isn't all that far off either.
That said, online schema migrations are a specialized tool designed for very big tables that take hours to run an ALTER TABLE on. If all your tables are small enough that alterations take less than a second or so, don't bother and just block the table for a bit. It's fine.
