The problem of going above 110 in maintenance is the cost; 2,000 points isn't nothing to laugh at. Maintenance is also not much of a factor until the late game, as your economic growth and warring should lower the part of maintenance in your budget.

As the game draws on, Maintenance becomes nicer and nicer, especially if the galaxy is quite peaceful. You will have the time to reach your maintenance limits, giving you quite an edge over the neighbourhood. Likewise, if most of your income comes from treaties, a low maintenance will allow you to build a much bigger armada than otherwise possible, while still being able to maintain it. (Taking 119 rather than 120 may be better as well, for the sneaky players among us)
