Actually, the score system as it was in early betas fixed this too. If your planet was reduced to rubble you kept your score, and were well placed to take advantage of the score bonuses for small planets hitting big ones.

there is another way too... a few rounds ago I made a very long suggestion where the universe could be kept in a steady state by declaring the largest planets each week 'winners' and resetting them, with a running total of past 'winners' giving the alliance score.

I've also posted a a thing or two about using PA-controlled roid-initiating bot planets to keep the number of roids in the universe at a 'nice' level, preventing stagnation in the endgame.
