How to get the DCFIFO constraints right for once and for all?

I'm not looking for a workaround, I'd like Intel to stop being incoherent and fix their primitives. There is no reason on earth a primitive needs to be constrained outside by the end-user itself.

Is that so complicated to embed all the necessary constraints into Quartus without the need to check on the forum and years old KDBs?

Xilinx is capable of it with their xpm library, why Intel can't? They have existed for years.

Feel free to close the issue once this is reported to be fixed.
