Lots of people care about it, and it's alive and kicking in-industry and being developed (Tcl 9 is imminent[0]).
I've had fun w Guile over the years (though actually never considered its "heaviness"); fun.
I'm constantly amazed at the professional love for Python; its got it's network effect in full-effect: lots of people, lots of software - there's just no denying that. But for Joy of Development, Tcl (and C) is still my go-to.
You probably know this, but speaking of embeddable Python and Tcl, Tcl is indeed embedded in Python if you're running Tkinter[1].
And Larry Wall thought routers were weird places to be ported to[2].
