Blockchain Applications moving from namecoin to bitcoin

[btc_enigma]

Lately I have seen applications move to blockchain for storing data instead of namecoin

There is a thread discussing this here https://forum.blockstack.org/t/why-is-namecoin-being-ignored-in-favor-of-bitcoin-based-key-value-stores/51/8

Mostly I see arguments saying that namecoin is not being actively developed which I don't buy into.  Thoughts ? It is really necessary to spam the bitcoin blockchain , when other blockchain can do the job very well and is designed for storing key/value pairs

why is it that important to see namecoin being developed further if it can handle pretty much anything that people currently throw at it. what will happen with the transactions when blocks get filled with data that gets usually stored in the namecoin blockchain but now are pumped into the bitcoin blockchain? delays? low priority transactions getting even lower in priority and have more delays as result?
