An additional delay of 200 milliseconds means loosing approximately 0.3%
of the revenue.
Do you really think this is going to be the key factor to prevent a
mining pool from being used?
There are lot of other factors, such as DoS protections, security,
privacy, variance, trust, algorithm to distribute shares, that are much
more important than that.

And having a 1 minute block actually reduces the payout variance 10x, so
miners will be happy for that. And many pool miners may opt to do solo
mining, and create new full-nodes.

The SPV traffic is minuscule. Bloom-filers are an ugly solution that
increases bandwidth and does not provide a real privacy solution.
Small improvements in the wire protocol can reduce the traffic two-fold.

Because having a 10 minute rate Bitcoin is a good Internet money. If you
have a 1 minute rate, then it can also be a retail payment method, an
virtual game trading payment method, a gambling, XXX-video renting 
(hey, it takes less than 10 minutes to see one of those :), and much more.

You can reach more billions by having near instant payments.
Don't tell me about the morning caffe, I would like that everyone is
buying their coffe with Bitcoin and there are millions of users before
we figure out how to do that off-chain.

Best regards,
 Sergio.
