Usually -- yes, the default ootb configuration will have projects backed 
by VC repositories, because the default set of markers is determined by 
the value of 'vc-handled-backends'.

But now the users will be able to extend that set of markers through 
customization.

I haven't been able to come up with anything more concrete than 
"builtin", and that's both a non-name and not exactly true since 
'transient' also exists. But "VC aware" might also fit the bill. It 
sounds more like an adjective, though, than a proper noun.

It difficult to come up with a name using a principle like that when the 
preceding effort was made to be able to accommodate the projects of 
different users with new usage patterns.

It is "VC aware" or maybe "VC friendly", and it works with projects in 
the shape of directory trees. But both characterizations can apply to 
e.g. Projectile as well. Except the latter is probably more flexible, 
and our backend is probably faster, especially over Tramp.

But if we just compare with the other builtin ('transient'), then its 
VC awareness is probably the key thing. And the customization options it 
has (which 'transient' doesn't).
