No.  You can mount the same dos directory/file with multiple posix paths
and use different settings for each posix path.  When you access the posix
path in cygwin, the setting of the specific posix path will be used.  /cygdrive
is just another posix path in this case.

FWIW, this question has little to do with the issue you have tested.  If
you're using /cygdrive/c, you're probably inside a bash shell.
Redirection inside of shells has always correctly set binmode/textmode
based on mount, afaik.

It was the case of redirection from the dos command line that the recent
changes were supposed to handle.  Since the only information available
to cygwin at startup is (essentially) the dos path, cygwin has to guess
at the posix path associated with the dos path.  It will use /cygdrive/x
only if the dos path isn't specifically found in the mount table.
