This trick is actually used by some banking apps.
They fill app their mobile apps with junk data just to make the APK/IPA bigger. So if they need to push an urgent update, they won't have users that can't update because their phones are full to the brim.
I know two Italian banks that do it, Unicredit and Intesa. The latter was on the news when a user found out that one of the filler files was a burp recording [1].

Doesnt this create an arms race situation where every 'critical' app claims a larger diskspace than necessary, just in case, and accelerates the issue?

But you still need a bunch of extra space to download and unpack the new version, and there are so many apps that need to share space, and a banking app should only need about 0.1% of a phone's storage...
Whoever gave them that idea was doing a bad deed.

Interesting, makes sense, seems to be bad precedent if everyone follows suit.
