Do they have to? Here in Europe it's at least 2main color systems
(and other continents may have their own specialized systems):
HKS and Pantone (with the largest palette).
HKS is adopted by some/many? printing color manufacturers. Pantone 
isn't.

As far as I may understand your claim, an open match table might collect
widely (world-wide?) spread color systems from different manufacturers?
There is, in my opinion, only one wich is spread widely enough to 
fullfill this
need. May be I am wrong?

Why should a vendor produce colors different from the main system(s), 
and
what might be her benefit?

Most printers/printshops (40 down to 6 people) I know are happy to rely 
on only
one or two producers.

None of them is able to provide even the full range of Pantone colors 
from stock.
They mix certain colors from the range they have available. Imo it's 
not likely they
want to put more pots of a completely different color systems from 
different vendors,
which stay half empty and that they cannot blend, in their stock.
Pantone offers a wide range of colors (and color samples), the 
standards are
guaranteed and customers are used to it.

How wide (world in mind) might an open matching system spread? How to 
guarantee
all color formulars are interoperable (chemical, physical)?

Don't misunderstand, I would very much appreciate an open standard - 
but for now
I don't think there are substantial needs or benefits in it.

Pantones numbers are meant to be used as and are commonly known as 
names.
Why should numbers not be used as names? Aah, this might lead to some 
philosophical discussion?
If so, sorry.
I don't mentioned it.

BTW, what is LGM?
