Because the spec allows implementation-defined serialization attributes,
I'm inclined to the view that if there's a user demand, implementors
will add the feature, and if enough implementors add it, it becomes
worth standardizing. Some of the existing options, such as
omit-content-type and suppress-indentation, got into the standard having
first appeared as Saxon extensions.
There's a steady trickle of requests to provide serialization options to
control things that shouldn't make any difference: empty tags, choice of
quotes for attribute delimiters, use of entities and character
references, details of indentation, etc etc. It's hard to know where to
draw the line.
The existence of non-conformant XML parsers isn't a use case that is
likely to carry much weight with the W3C WGs, unless perhaps it's a
non-conformance that is very widespread and exists for a good reason,
such as conflicts between different specifications.

Hi,
I noticed this question on stackoverflow:

losed-tags-for-empty-node-sql-server-2008
Apparently SQLServer has trouble processing the short notation of empty
elements. It got me thinking though, the new serialization spec gives
quite some strength for tweaking the output, but not influence tiny things
like notation of empty elements. Maybe this isn't the most appropriate
list asking this, but I'm asking here anyhow: hasn't it been given thought
to add some flags that allow end users to tweak the output more
extensively? Like a short-empty-elements="no", things like that?
I also used to work with a language that allowed so-called productions
from in-memory trees. (It was a language much alike XSLT, but older.) It
allowed writing production rules for each element, to control how things
should be serialized. Not sure how that would help here, but thought I'd
mention it anyway..
Cheers,
Geert
