Not in favor. IMO people should use RSK instead, which is sidechain of Bitcoin network and heavily tied to Bitcoin since it only peg Bitcoin and use merge mining with Bitcoin network. That way, more people would use Bitcoin indirectly while letting Bitcoin mainly used as payment method/currency.
P.S. While different Bitcoin sidechain exist, i'm not sure how decentralized is it.
dont be so quick judge
bitcoin doesnt really have a proper well know sunbetwork. even less one one thats only designed to operate with bitcoin and bitcoin alone
root stock is a subnetwork bridge. it allows bitcoin and ethereum
just becasue rootstock give away some RKS if some bitcoin mining pools put a rootstock blockheight hash into a bitcoin coinbase reward output
does not mean its integrated to only be function for bitcoin
rootstock can continue on making its own new blocks without paying a pool to mile stone its chain at certain random heights(include a rootstock hash in a bitcoin block)
rootstock can also function even if it only handles eth erc20 tokens
same goes for liquid
Ln has always been a cross border subnet bridge. even its first transaction was done using litecoin, even poons whitepaper called it a cross platform network
..
ethereum has HUNDREDS of subnetworks and yes majority are bridge subnetworks
but bitcoin is slacking behind. it needs to stop wasting years on half assed subnetwork bridges and "conservative.. patience" that after years have not met promises..and maybe start a completely new subnetwork. one that actually solely functions as a subnetwork for bitcoin. and has some integrity, purpose it can meet, utility it can use, some policy and accountability of security. and let that grow into something with some niche utility like "bitcoin backed NFT"
