There should be no or almost no drawbacks, because that desktop environment isn't required to run those applications. This is exactly what I do on a Kubuntu 14.04 machine that still has a good old KDE/Plasma4 desktop, and I do something similar on my Mac where it is evidently not possible to run a full Plasma desktop environment.

For the most part those will probably not interest you, if not you can install/run them manually. The most important things (kdeinit5, kded5 and kwalletd5) should get started automatically.

Only setting QT_QPA_PLATFORMTHEME=kde makes dolphin crash at the first startup (second try always works) and sends kmail
into in infinite loop at start, I already tried that some time ago.

Setting also KDE_FULL_SESSION=1 and KDE_SESSION_VERSION=5 makes it all work like a charm! Setttings are saved, file open
dialoges are now really KDE and not some minmimalistic version and a number of other idiosyncrasies...

Thanks a lot!

Is there some KDE wiki site that can be used to document that? Is the right place?
