This is a great addition!
I noticed that the new code uses GDAL VSI* calls to open the image in
memory, essentially adding a GDAL dependency on mapwmslayer.c which was
not there in 5.6. I'm okay with this dependency since GDAL was already
recommended in previous releases anyway in order to support reprojection
of cascaded requests, so I have updated the configure script to check
this dependency and the README.CONFIGURE to document it in r10548.
