It's probably because an FPU is easy to add to a design. It takes exactly the same amount of logic and pins to tell the 68030 that there is no FPU (equation for the BERR signal is equal to the FPU_CS equation - for those who know a few details about the '030).
"If you generate that signal anyway, you might as well add the socket
" is probably what designers back in the days were thinking. However, if you do the math, then...:
Sorry - that was the technical explanation of "an FPU would jeopardize the high fastmem speed
". I tend to go into detail too much...
