Hi, you're right. It's a long time but we are still not sure if Laravel community wants it ;-).
We had few implementation requests but when we asked for some community/user support during implementation there was no interest.
In case we decided to implement it we need some users for test/helping us with implementation because we don't know Laravel at all.
Will you be able to provide us some test models including the real ones so we can see all requirements? In will you be able to do some testing/feedbacking during alfa/beta stage?
If so, please contact me directly at [email protected] for more details. Thanks!
