Looks like a nice setup though.
I have to guess because:

#1 The alts are built to fit "existing" locations which may be very tight. I have some that literally clear by 1-2 mm's...

#2 They are, no matter how "custom" they claim they are, built on existing "industry" case sizes & offsets. While companies like Balmar and E-Maax do cast their own cases the case is basically a replica of Delco 130D, 10DN, 10SI, 12SI, Motorolla, J-200 etc. etc...


There are some new technologies coming that will drastically boost the capability of a small case alt but it is still a year or two out..
