No.

The current rate is different. But it is a user mistake. It has been
a design decision by Leslie Lamport that optional arguments may be
separated by spaces. The end of a line counts as a space. \\[5in]
leaves an additional space of 5in after the line. \\[0,1] is missing
a unit, however. As you noticed, writing something like {} or \relax
will be sufficient for separating the argument.
Please also notice that you are completely off-topic on this list:
this list is about teTeX. If this would have been a bug, it would
have been in TeX or LaTeX, but not in teTeX. teTeX bugs involve files
that are not found, size problems, bad format files and similar stuff
where interaction with the environment is concerned.
