It's by design, though both ways have their pros and cons.
If I remember correctly VisualStudio has a nice (if complicated to
implement) solution, it never saved the superfluous whitespaces, but
graphically, in the editor it appeared to leave them alone so it didn't
cause you to re-indent while editing after a save.

It could be made an option, for example as in this this pull request:
Of course it would take someone to update it and try and get it merged.
Speaking only for myself, I'd never use this option/feature, and so,
with my limited time, have never dedicated any towards reviewing and
You could also do as John mentioned and write a little script to do it
as you like, and you could even make it a command for "Send Selection to
Command" so that you could do <Ctrl>+a, <Ctrl>+1, <Ctrl>+s to strip the
whole file while saving, to your preference.
For inspiration, there is a script in Geany's scripts directory called
`rstrip-whitespace.py` which could be trivially adapted to do as above.
