is getting a bit old. Perhaps you should pick one that more accurately
reflects then subject at hand?

This is, although buggy, perfectly normal. What LaTeX calls OT1 is, as
mentioned in the fontinst manual, really five different encodings (all of
which were cooked up by Knuth) and thus some commands fail for some fonts.
This is yet another reason T1 is preferable to OT1 as text encoding.
The differences are formally spelled out in

Again, this bug is documented.

Yes, more of the same problem.

Yes, it could be argued that fontsmpl.tex is incorrect, as much of what it
will show is "broken by design", but OTOH I don't think it has any special
provisions for OT1 at all. (fontsmpl.tex just goes ahead and tests a bunch
of accents and characters that aren't in that font.)

These things are the way they are for compatibility with the Computer
Modern fonts. Had it been done as an orthodox interpretation of ot1enc.def
would have required, then very many documents written using the CM fonts
would have been wrong if set with other fonts. In the early nineties, the
CM fonts weighted much more heavily as a standard than did LaTeX2e's NFSS.
