So there is no real point to collecting the flags in the first place?
I.e. we could also get rid of the variable and have the single current
user of the variable add the flag directly on the commandline too. Or
otherwise, we could change the other users and collect all flags with
this variable. Pre-existing of course, but ideally, we could avoid the
mishmash.
