Is Tcl still a thing? At my first job I extended with a set of data-processing commands.

Many of the big EDA (Electronic Design Automation) tools continue to use tcl for the command line interface. Some users have created quite complex, customizable design flows spanning multiple tools and even development infrastructure (much, much more than just "stitching tools together) using tcl.

It is still actively developed and used, yeah. People tend to mention the fpga scene most, tcl is the predominant language there, but I use it mostly with or along side audio/visual software.

I used it for scripting routers, more than anything else.

I guess expect became something almost popular enough to be considered external to TCL in the end, too.
