Removing red and blue altars from Ubers

Am I correct that the red and blue altars do not affect Uber boss fights? Since we have the new atlas, wouldn’t it be much clearer to simply remove them from the fragment area? The reason they were there in the first place was that all fragments and maps went into one place. There does not seem to be any reason for them to remain there now.

They could also make the Maven invitation much more noticeable in the UI for Ubers. For example, they could make the fragment area light up when the Maven invitation is clicked.
