This is the first I am hearing of it. I know in the past that you could request larger storage size, however, our size limits were not primarily due to Intune, they are also due to WSUS, as there is a max file size limit for WSUS, and built-in to SCUP. We have some plans to increase the max file size, and background work is happening for that now, but I do not expect to support larger installers until next year at the earliest.
