If a mechanism was dodgy in the first place and was dubious as a part of
plain text, then yes.

If a mechanism is clearly a necessary part of the text model, but takes
a while to catch on, because it is inherently complicated to implement
and roll out, then no.

Remember, it took a good part of a decade for significant support of
combining marks to start appearing in Unicode implementations. Even
longer for fairly good support of the Indic rendering models.

If you are worried about the emoji tag sequence mechanism, then I'd say
no. Once the use of regional indicator symbols caught on to represent
flag emoji, that basically settled the question of whether pictographic
symbols for flags were a part of plain text. Once the emoji tag
sequences are rolled out for the regional flags (a process I can surmise
is happening even now as we debate this), there will be no going back.
You can be guaranteed, given the current attention to Brexit, that the
tag sequence for the Scotland flag, at least, will leap up the emoji
frequency list almost immediately. And that data will end up being
supported essentially forever.
