I absolutely agree with you. Especially since the DMP-BDT500 doesn't have the ability to go back to a previous version (according to the firmware download web page, see the excerpt below).
My old Samsung BD-UP5000 would allow going back to previous firmware versions; and this was indeed required once or twice when a bad firmware came out (Samsung would eventually fix the bad firmware, but it took them awhile).
So for now, I have 1.31 on a CD-R, but I am waiting for something later...

But the following note is from the download page about firmware versions:
If the firmware version currently installed on the Panasonic Blu-ray Disc™ Player is the same or more recent than the firmware version on the update disc, "UNSUP/PORT" will be displayed for approximately 5 seconds on the front display of the Panasonic Blu-ray Disc™ Player. In this case, an update is unnecessary - please remove the disc.

Interestingly, the source code (for something?) appears to be available from here:http://panasonic.net/avc/oss/bdplayer/AWBPP12.html
But most of these I recognize as standard linux things. I haven't looked through them to see if there is anything Panasonic specific, or if these are just provided because they have to be via the GNU license.
