Hm. If LaTeX don't add spacing there, then LyX shouldn't
either, unless LyX also add spaces in the output. But there
will be cases where people want no spaces, so I think
LyX shouldn't add anything.
Agreed.
I think you are both right concerning output there shouldn't be added
anything in LyX that isn't needed in LaTeX.
I think what the could be useful is a better (visual) user feedback on
wheather there'll be /real/ space or not in the output.
I cite the suggestions in

If the user knows exactly where the equation ends and if there's a space
added there'll be no surprises in output.
The option "preview" isn't enabled by default. If a user has set it in
his preferences the latter example ("x2 = 1") will not be rendered as
preview if the space hasn't been added.
I may need to remind that I am still working on 1.4.3 (Ubuntu) and
haven't tested the 1.5.x realeases, yet.
Kind regards,
