No. Some tk widgets map their values to Tcl variables. Other similar
interfaces exist. It is handy to map them to an instance variable but
for that it is necessary to have the namespaced version available. Of
course you could always do it through globals, but that is just more
messy.

I've seen it happen with scripts given to [after]. I was actually
very surprised by this, but at some point I was witnessing those
scripts becoming strings and thus losing the original Tcl_Objs inside
them (the scripts were built as lists).
