Can I use arduino bootloader with atmega128?

Hello~ I’m arduino beginner
Today I saw this in the first part of arduino bootloader code.

/* Serial Bootloader for Atmel megaAVR Controllers /
/
/
/
tested with ATmega8, ATmega128 and ATmega168 /
/
should work with other mega’s, see code for details /
/
/
/
ATmegaBOOT.c */

Can I use arduino bootloader with atmega128? wiring and arduino share bootloader?
Or it’s just fossil of old code?

It should work, but you’ll want to recompile it for the atmega128 which will be a bit different to the 168; ie make a new .hex after checking the mcu and f_cpu vars in the makefile rather than using the existing one.
