Anyone using non-instantiated signal (instantiate: false)

[erikbosch]

The instantiate: false attribute is described in VSS documentation but not actively used in current VSS standard catalog. It is intended to give something similar to C++ static class members, but that is not always easy to represent in all target environments/formats, i.e. not necessarily easy to support in all existing or future vss-tools. By that reason I would like to know:

• Is there someone using instantiate: false in their own (private) VSS implementation?
• If not, would be a candidate for removal, or alternatively state that it not will be accepted in standard catalog (i.e. error when using --strict mode)?

I can confirm we are not using it.
