I wasn't, no, I was comparing it with what it is. In particular, the
"what's on now/next in teletext" is exactly like an EPG is now.

This is different, and I was certainly not confusing it at all. The
purpose of this is to allow video recording to follow actual schedules
rather than the published ones, which EPGs do *not* do.
You appear very unclear about what these technologies do.
For the record, I have a PDC capable video recorder, but I cannot use it
because PDC was abandoned on pressure from "copyright holders", whereas
EPGs have not been. I presume this is because EPGs do not reflect late
schedule changes.
I would also note that late model analogue TVs, video recorders and
other machines would set their time from teletext broadcasts.
