your idea has many faults.
1 that there should only be one source of income. the blockreward
2 that only one implementation should receive the 1% of block reward
3 that there should only be one implementation
4 that automatically getting $130 every 10 minutes means those in that team will do better
5 that automatically getting funds will make them do things the community want.
imagine it though. if say 500 people-5000 people wanted dynamic blocks. it needed say only 10 lines of code to change. and each of them put say $10 bounty in.
that is $5k-$50k to add dynamics
or
devs get $130 every 10 minutes ($6,832,800 a year).. and then while the devs are getting paid.. there is no structure or community agreement on what should be done by the devs.
infact the devs decide to grab an altcoin from a private elements project. tweak it a little and try to coax the community into accepting it as thier attempt at doing something. and 2 years later still debate with the community as to how utopian it is.
(netting them another $13.66mill wasting time) as an example.
so you tell me what is better
$5k-$50k for dynamics 10 lines of code
$500-$5k for txsigoplimit 1 lines of code
and so on
or automatic payments with no structure/target
