Yes, if you don't understand consequences, don't touch it.
TCL/Tk issue is fundamentally different from glib2 which you're bringing
up as example. (In particular, glib2 is corner stone for a lot of GNU
packages, while TCL and Tk isn't. In addition, fallout is way less
obvious and harder to notice, unless you do use those packages. That, as
it seems, you don't.)
