6		1) postgis raster has GUCS that affect it's behavior - http://postgis.net/docs/manual-2.4/reference.html#PostGIS_GUC it would seem a bit odd to register gucs in postgis for a separate extesnion. postgis_sfcgal actually has a similar issue but not quite since it's gucs are to swap out postgis same named functions with its own. So utiltizing the backend doesn't actually require postgis_sfcgal to be installed.

8	8	2) postgis rasters whole index framework is built on top of postgis geometry. Granted this doesn't affect install and deinstall, but it's intimate to me.
