(Not really following this thread... and not a real
fan of `tabulated-list-mode', which is anyway too
limited/restrictive...)

Why the doubt?

Of course some users would sometimes want to
interactively remove a column from the current
display.  Why wouldn't they?  That seems like a
no-brainer to me.  Think Dired/ls, or the bookmark
list (toggle showing file names).  

Why would users want to be able to sort columns
but not also be able to move them around or
hide/remove them, including interactively?

OK, you said "many users".  There's room for lots
of doubt about anything in Emacs, if the qualifier
"many" is applied.  Whether being able to hide
columns interactively is a useful feature for
Emacs to add shouldn't depend on whether "many"
users would likely use it.  Not if someone is
willing to add that feature.  Why not?
