This is the opportunity to write a wish list

That's the problem. I hope the EU --the customer here-- realizes that free software is essentially beekeeping. You need to make sure the bees are happy, giving them flowers and forest; in return, the bees will give you honey and even pollinate your vegetables. You can't sign a contract with them trying to regulate the amount of honey they must produce, or negotiate how many flowers you are willing to provide them. Of course, if the bees don't produce honey after some time, you may consider finding other bees; but as long as the bees do their job, one should just keep them.

Of course, the EU needs to make sure which projects it should protect, to not waste taxpayer money.
