Feature request: Field incompatible-with in library.properties

[bengtmartensson]

Some libraries are incompatible with others. Fact of life. I propose a field incompatible-with in library.properties, analogues to depends and with the same semantic (several entries divided by commas), but with the opposite semantic: The library manager should refuse to install a library if any of the libraries in incompatible-with is present. Ideally there should be a granularity down to version too, but let's leave that out for the moment (there is no versions in depends either).

Only in this way it is possible to cleanly publish a completely compatible replacement for an existing library.

I like the concept, but refusing to install a library because incompatible with other ones already present would not be ideal.
It is down to the sketch level that you want such incompatibility to alert the user

Also, often such "incompatible" libraries can still be made compatible by e.g. including an "ImprovedFoo.h" or "OriginalFoo.h" header file that is unique to the improved and/or original version, so a sketch can select one or the other.
