That's not pollution. We already had mysqlnd specific bugs or cases
where we would
have liked to detect at runtime which backend is used. That's a rather
common
need.

Not needed, pollution.
mysqli has client info, mysql has mysql_get_client_info(). With the
mysql[i] extensions the info which library is used can be retrieved with
a simple stristr() call using the API that is there to tell you the
client [library] version [string]: *_client_info(). Even stinky PDO has
a version string, although documented as int: PDO::ATTR_CLIENT_VERSION.

It could still be useful and won't hurt to have it.

Original issue was "bogus" (persistent connections).
Too few relevant differences between mysqlnd and libmysql otherwise and
none that you can't easily detect by e.g. using mysqli->client_info. No
need for an extra constant.

> And you really should be checking if mysql*.allow_persistent is
on or off anyway
We don't need hide php warnings, so if php trows a understandable
warning in such a case, then that would be sufficient.
So, for my use case this is not valid anymore then, Thanks;)
But as long as mysqlnd behaves differently then the old mysql client, I
would vote for such a constant anyway. Or you can close with reference
to the first comment(2:21) on how to detect mysqlnd if you absolutely
need to know about it in code.

"p:" is allowed always since PHP 5.3.0. You only get a warning when
someone has disabled persistent connections with mysqli.allow_persistent
ini option. You don't need to know whether it's mysqlnd or libmysql that
is used. And you really should be checking if mysql*.allow_persistent is
on or off anyway. :)
