I see the tabularray issue simply as an example that \empty is not as
reliable as we thought. There might be other LaTeX packages throwing
errors on \\\empty.
The proposed workaround may be enough for tabularray, but may not be for
other packages.

I do not think that users will clearly understand the purpose of such
defcustom. It is solving some very narrow edge case, and it is unclear
why we would need to advertise changing it in customize interface.
I'd prefer to keep it as defconst, but maybe mention in the docstring
that it can still be set to "\\empty" as another semi-safe value. At the
user's own risk.
