DPMI is used not only for entering the protected mode, but also for
all system calls issued by the low-level library functions.  Memory
allocation, file I/O (including reading the program into extended
memory from its .exe file), hooking hardware interrupts, support for
debugging programs--all these and more are handled via DPMI services,
because issuing real-mode interrupts from a protected-mode program is
a tricky business.

If you remove DPMI, you will have to rewrite all that low-level stuff
(or give up the functions which need it).
