i wonder why xmr development were focused on thing that we cannot see such
" increase of anonimity " 
arent their coin anon already
how would we rate their improvement
sound like a bunch of hot air to me LOL
Nice concern trolling, but I think you missed the memo that would have told you that anonymity, like fungibility, isn't a yes/no proposition in cryptosystems, but a more/less proposition. Thankfully the Monero team has cryptographers that are actively working to reduce or eliminate attack vectors, in this case with I2p developers. Would you like to dig a deeper hole and second guess I2p developers too?
