I don't think it would hurt anything if it fits your style. It wouldn't really fit mine I don't think.100% in agreement with getting all of your features at level 1. (Assuming no level-by-level MCing, though). Leveling just scales your abilities.
One thought for anyone pursuing it for Extra Attack. Allow the feature even at level 1, but with a -4 penalty. Each level the penalty is lessened by 1 point, so by 5th level it is gone completely.
1st: -4
2nd: -3
3rd: -2
4th: -1
5th+: no penalty
