Alignments are permanent? When pigs fly maybe.
The OP says they’ve hit nasty potholes over the winter. It only takes one nasty pothole to knock the front end out of alignment or damage something which then leads to the alignment being off.
Inspecting the alignment is the proper thing to do when any suspension parts are changed as even a few thousandths of an inch here and there with a suspension part can translate to fractions of degrees; or even full degrees.
