D7 schema updates need to be ported to D8 (?)

Problem/Motivation

I noticed that some schema changes (and probably related functionality) have be made to the module on the D7 branch that haven't yet been ported to D8.

There are a handful of commits on the D7 branch, from Feb 2019 to Dec 2020 that make changes to the H5P module's schema:
https://git.drupalcode.org/project/h5p/-/commits/7.x-1.x/h5p.install

However, the h5p.install file in the most recent D8 release candidate does not include these schema changes and I'm guessing the related changes to functionality also are not yet included in D8.

Proposed resolution

I'm not sure if this even needs to be resolved, but I though I'd bring this to the attention of the maintainers. I encountered this issue because I am in the middle of implementing a migration of data from a D7 site to a D8 site. An update to the h5p module was recently applied to the site that I'm working on and this update included the schema updates. It may be that I can ignore, in my site migration, the new database table and columns that are added as part of the update. However, if these schema changes are later applied to the D8 branch, I will need to update my migration, meaning I will need to track this issue.
