I wanted to keep these tests focused on the `FEAT_*` identifiers and to remove
the need of dealing with the less strict "description" content, which makes it
tricky to autogenerate the check lines. The set of extensions for each
architecture version is also stable, which reduces the value of going for
autogenerated tests in this case.
