A friend of mine, a pianist, arranger and composer who also teaches
music at Leipzig's academy of music and theater, writes his
compositions in Finale [1] and exchanges them with other people as
MusicXML. MusicXML supports overlapping staff groups, as can be seen
in example 41f-StaffGroups-Overlapping.xml on [2]. MusicXML's slurs
are "composed" of milestone elements, as can be seen in [3], adopting
a popular method to represent overlap in XML.
I don't have statistics about how many contemporary composers write
music conventionally on sheets or electronically with Finale etc., but
I guess that most of them use software nowadays. And this software
more likely than not has XML as an exchange or even as a native
storage format. And that XML interchange format is able to represent
overlap.

You can express or represent (I regard both terms as synonymous
wrt the
current discussion) such an overlap in XML, see for example how the
Common Music Notation handles overlap in beams or slurs (search for
"overlap" on [1]). It's just that you cannot express it using
overlapping elements.

The fact is that no conductor in the world is using CMN, do they? :)
Just the "old-fashioned", non-xml-based musical scores ...
If "XML is one's language" and they have to conduct an orchestra,
what are the chances they will use CMN and not the "old-fashioned",
non-xml-based musical scores ?
Does even a single such example exist?
Luckily, no one has ever tried to represent a Venn diagram with XML...
"If the only tool you have is a hammer, it is tempting to treat
everything as if it were a nail"
(https://en.wikipedia.org/wiki/Law_of_the_instrument
<https://en.wikipedia.org/wiki/Law_of_the_instrument>)
To quote from this source:
The notion of a /golden hammer,/ "a familiar technology or concept
applied obsessively to many software problems", was introduced into
information technology
<https://en.wikipedia.org/wiki/Information_technology> literature in
1998 as an anti-pattern <https://en.wikipedia.org/wiki/Anti-pattern>:
a programming practice to be avoided.
Software developer José M. Gilgado has written that the law is still
relevant in the 21st century and is highly applicable to software
development. Many times software developers, he observed, "tend to
use the same known tools to do a completely new different project
with new constraints". He blamed this on "the comfort zone
<https://en.wikipedia.org/wiki/Comfort_zone> state where you don't
change anything to avoid risk. The problem with using the same tools
every time you can is that you don't have enough arguments to make a
choice because you have nothing to compare to and is limiting your
knowledge." The solution is "to keep looking for the best possible
choice, even if we aren't very familiar with it".
