You want to enable LRA by default for your distro, but you don't want to rebuild all the packages with that modification? It's like .. shipping a distro with a new compiler, which potentially can't compile the distro packages (correctly), so instead we secretly use an older compiler to build the packages .... ? Is that normal practice? Sorry, sounds like a mess to me.
