Fix #[issue number]

Technically it is possible, but we should consider the compatible issue of flavor traditional.

+1 This looks very interesting - looking forward to it :)

It feels like the new router expressions are to provide more powerful matching, so maybe it is acceptable for them to go beyond traditional capabilities..? :)

@chronolaw Could you clarify why it causes compatibility issue with traditional? traditional is feature frozen at this point and we do not plan on porting this feature to it.

We should add a new field in the route schema, which is shared by traditional and traditional_compatible.

If you are right, then we can only implement it in traditional_compatible

This is a expressions only feature, we should not add it to traditional or traditional_compatible, they are feature frozen.
