That is correct. By default extensions don't need to declare compatibility
with specific GNOME Shell versions since 3.21.92 (in earlier versions, the
Shell interfaces that extensions use changed more frequently).

If that option had any effect, it would be to disable some of your
extensions. Extensions that say they are compatible with Shell 3.28 should
never be affected by it. gpaste and "removable drive menu" seem to both
be from packages that are updated in sync with the rest of GNOME 3.28,
so I would expect that they declare compatibility with Shell 3.28 and are
unaffected by extension version validation.

That sounds like it might be an intermittent bug that doesn't necessarily
depend on the enabled state of those extensions, unfortunately.

FYI, this is the package containing the "removable drive menu" extension.
