I understand (especially for f-strings!) - I'm in a similar boat with my own
project (qutebrowser[1]), but I didn't dare to drop support for 3.5 yet.

But what I don't understand: How are you going to use e.g. f-strings if you
need to keep support for 2.7?

Not for me - qutebrowser currently still only supports PyQt5. If PySide2
support was introduced, from qutebrowser's view it'd be fine to only support
that on 3.6+. Other projects might feel different though.
