Which shortcuts should be in our library and which not?

[Steffen]

Although some kind of formatted keyword could solve that problem.

I would find the presence of the simple wheel+tyre assemblies more helpful.
Doing that avoids all the hassle of
- having to define a new syntax
- adjust all the parsers
- make people understand how that is intended to work

Instead, just offering the simple wheel+tyre assmblies shows the possible combinations.
They really do not hurt.
The amount of possible combinations still is small compared to the overall amount of files.
For example, each time we do a renumbering with a MOVED-TO, we are creating small files.

From my perspective, still releasing the wheel+tyre assemblies officially is the way to go.
