I think that is a fair argument.

This is how I worked around recently. This has a downside though, it
doesn't let you easily use markup in the subtitle (in my case I wanted
to use =keyword=). Of course this can be resolved by putting in by hand.

Same goes here, but I would say the #+BEAMER: solution is better in
comparison. A subtitle is still part of the title, that means it
probably should be easily visible.

Given my above comment about visibility, one might then argue having a
#+BEAMER: line does not serve that purpose either when the headline is
folded. I'm not sure what is more important here, consistency between
backends[1] or readability/usability(?). It would be interesting to hear
what others think about this.

Hopefully I was clear.

Cheers,

Footnotes:

[1] IMO, an important reason for using org is backend agnostic markup.
