On the other hand, a stable testnet is somewhat important for people that want to debug and test merchant sites.

This time, it took me about two days to generate any coins on the testnet, the coins the faucet sent me never arrived (and still, it insisted it had sent me coins, I wasn't able to repeat it).

For debugging your own sites, a testnet-in-a-box setup is nice and stable, completely under your control, and has a good supply of mature coins to debug with. See http://sourceforge.net/projects/bitcoin/files/Bitcoin/testnet-in-a-box/
