Yes, it appears as if I'm looking for both. Handling the descriptors
and getting them there in the first place (either via fixups or talking
to the stations).

I don't expect you to dive in and do the work. I was more interested in
hearing if there are plans in that direction. Having someone look at
potential patches is highly appreciated.

I've looked at AvFormatDecoder::ScanTeletextCaptions and saw it handles
only page types 1 (initial teletext page) and 2 (teletext subtitle page)
but not 5 (teletext subtitle page for hearing impaired people).

Is there a way to signal this difference in target audience?

Can you give me a hint on where to look for a place to hook up a
function that injects the correct addition to the teletext descriptor of
the PMT depending on the DVB ids?
