Yep, it's safe and possible to do on pre-PCH as well. For panel fitting we do need to do an actual power cycle when going from non-native back to native iirc, but we can still leave them unlocked so we don't have to worry about the lock/unlock sequence everywhere.
Hidden in the unlock patch was a call to intel_lvds_disable from intel_lvds_prepare -- that *always* turns off the LVDS for mode setting. Do we care enough about LVDS mode setting performance that we should try leave the optimization in place that doesn't turn off the backlight when switching between modes?
We hate flicker right? But generally yes it's safer to just turn it off all the time.
