Indeed.

As Hans pointed out to me, the single ones aren't really used
typographically, as far as ConTeXt is concerned.

Ah, hmm. A point I hadn't really considered.
I've considered using TeX 'n' ANSI as the "companion" font anyway, so
that is very plausible as a workaround.

I think it's there to help compose a perthousand/permyriad symbol.

I investigated it, and Tcedilla is really a mislabeled Tcommaaccent.

I asked Hans. He didn't want it, didn't use it, and thought it was ugly.
Beauty over truth. :)

I thought it was a mis-labeled dcroat.
(However, these names within fonts are awfully fluid. I wouldn't call it
that for the stroked-d in Vietnamese, but that seems to be what the
Adobe Glyph List favors.)

as above.

That was my view on it.
