Romfs is used quite extensively in the uClinux space, and mostly on very small flash setups (can be as small as 1MB of flash). Any filesystem size increase would not be welcomed :-)
But ofcourse as long as the romfs filesystem code still supports the older version there is no problem (and it looks like it does).
