Because if your ROM binary consists of something along these lines:

800: LDX #00
802: LDA #$C1
804: JSR $FDED
807: JMP $0017
80A: asc "Hello World!"
817: (code continues)

you will almost certainly lose "code sync" during the string at 0xA and end up disassembling incorrectly when you get back to code at 817.

Well, your implication was that you'd discovered some amazing way to make games emulate faster that MAMEdev hadn't. Meanwhile we do use DRC, which gives equivalent run-time performance to static recompilation while avoiding the code/data problem entirely. So I'm still fuzzy on why this is even a thing.
