Yes. proj-dev-data is >500MB (also containing two extra huge grids with of 80
MB & 73 MB each; the latter for just one state in Germany).

Putting it in the regular proj directory from within QGIS might also not be
possible, when a regular user runs QGIS.  And internet access to download is
also not a given.

In OSGeo4W this isn't a problem.  Downloading from within the standalone
installer could be an option, but that kind of ruins the point of having a
standalone installer.
