https://www.openstreetmap.org/way/1329312751/history - here it is clearly not highway=trunk

Philet2137 is this time basing edit on a different type of official paper, E-road routing

for some reason E75 was not moved to A1/S7 and still goes through city center

luckily for residents it is not anymore very important road, definitely not on national scale so highway=trunk is extremely dubious - especially with "E75 is there" as sole justification
