I need a function that will turn on the tool bar from
switch-to-buffer-* family of functions, and then cause adjustment of
frame glyphs from set-window-buffer, via apply_window_adjustment.  If
you have a suggestion for how to do this, please tell.

Similar, yes.  But that a separate code, and it cannot be shared with
the menu bar, because the tab bar needs to know on the C level which
tab was clicked (the latter is a consequence of the fact that tab bar
support was copied from tool bar support code).

That similar problems with tool bar might go unnoticed because the
code is never run.

Will do.
