It does not matter a bit whether any other tool know about the xattrs.
Binaries will not change after they are created to require changing
the attributes. And it is no problem to not back the data up etc.
One really doesn't want to waste these resources.

And as far as the size limitation is concerned. It depends on the
limit, which I don't know off hand. But really, really big binaries
don't have to be treated like this anyway. They are not started
frequently enough to justify this.
