I see no evidences that launching konsole or xterm using menu or krunner 
causes starting bash as a login shell. I added a "logger" call to 
~/.bash_profile and log entries appear during login only.

SDDM does read /etc/profile and ~/.profile when starting a user session:
https://sources.debian.org/src/sddm/0.20.0-1/data/scripts/Xsession/
(wayland-session is a sibling file). I do not like that a part of code 
is similar, but not identical to /etc/X11/Xsession from x11-common. 
Ideally there should be no code duplication.

I expect that GDM contains similar code reading /etc/profile and 
~/.profile. LightDM Ubuntu package (but not Debian one) has it.

I suspect that startplasma does a bit more and transfers environment 
variables to systemd user session. The reason is the following.

plasma X11:

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/added-by-etc-profile-d
systemctl --user show-environment | grep '^PATH'
PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/added-by-etc-profile-d

fluxbox

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/added-by-etc-profile-d
systemctl --user show-environment | grep '^PATH'
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/added-by-user-config-environment-d

Notice that a component from ~/.config/evironment.d appears only in 
systemd and only in the case of fluxbox.
