But doesn't the POR activate on reset?  If so, the POR (IIRC) is
essentially an RC cirecuit inside the PIC, and is rated for a certian
range of time, but not calibrated...  You could disable the POR when you
load the bootloader, but then you're getting rid of a useful function
just so you can program through the MCLR.  You could also, I suppose,
calibrate it when you load the bootloader and take it into account, use
the watchdog and a crystal to find temperature and compensate for
temperature changes.
