Why can't LED full-color wall washing lamps from different manufacturers be used together?

The same lamp in a lighting project is basically provided by the same manufacturer, but it is often troublesome to find another one to maintain it after a while, such as LED full-color wall washing lamp, which is difficult for different manufacturers to debug together. Why? First of all, the LED full-color wall washing lamp has a driving IC, and each manufacturer may be a little different here; Secondly, electronic products are updated very quickly, and the old specifications of IC may have been discontinued, which is also a big reason why there is no match for later maintenance; There is also a difference in the wiring scheme and wiring mode of each manufacturer. Even if they can be used together, they need professional personnel to debug them, rather than simply docking them.
