I am surprised to read that the Russians intend to jettison the Pirs module sometime this year. Was it always intended that Pirs was to be temporary or did it just degrade faster than planned?

I am unsure if it was always planned but it needs to go if the Russian MPLM will be docked permanently.

I don't know about it being "always" planned, but the Russians had it in their plans to get rid of Pirs quite a number of years ago when the new science module was ready.
The main thing about the current ISS configuration is they have the Poisk module on the upper port, which gives them one more docking port for Soyuz than they previously had as the upper port was originally going to be the location of the Russian solar array tower. Pirs also originally had an operational design life of only five years and it has lasted far longer than that.
