Seeing as your starter stays engaged and running typically up to 45 or 50% N1...how do you imagine the starter might be stressed allowing it to drive the engine to it's maximum motoring RPM?
It isn't. The starter is going to stay engaged for the duration of the start, anyway, still being driven until it's cut-out point. That's the case regardless of when the fuel is introduced. If you happen to be flying an aircraft with a starter-generator, then it's not an issue at all, because that starter is going to stop driving by function of speed anyway, and it's always connected the powerplant.
A little research will find that your engine manufacturer will recommend allowing the starter to drive the engine to max motoring RPM in order to achieve coolest start temps and maximum engine life. The RPM specified in the start procedure will be a minimum speed before introducing fuel.
