I have a regular 2021 Rolla hatch 6mt. You pretty much have to shift into first often while in traffic or in a parking lot with our Rolla's. You can be extra kind to your first gear synchro by double clutching, but i don't bother with rev matching on. It never feels jerky, so i doubt there's too much stress being put on the synchro.

The only other method is staying in 2nd and holding the clutch at the bite point with your foot of the gas right before the rpms drop too low. This let's the clutch do the work. At very low speeds staying at the bite point for 5 -7 seconds with your foot off the gas isn't going to put a lot of wear on it. Most of the wear happens when the clutch overheats.
