You are being paranoid. It is a valid experiment in itself to find out if

Those are hypergolicly fueled engines using N2O4 and UDMH, and they
don't trust the Soyuz, whose motors use the same propellants, after six
months.

I thought the Soyuz' shelf life was more an issue with its batteries, not
its thrusters (?)...
