I think the effort required to remove testnet entirely would be too much to 
work on. Replacing it with something else is a better idea to minimize 
disruption.

In the mean time, we need to figure out a process to at least lock down the 
testnet3 network so that no new blocks can be mined while the replacement 
chain is commissioned. Is there a BIP with a procedure for replacing 
testnet? How was it done last time?

It has always been very clearly communicated that if testnet starts being 
valued or traded it will 
be reset. There's some legitimate debate over parameters in a reset here, 
but in the mean time 
testnet3 has ceased to serve its intended purpose as a valueless test 
platform. Thus, it should at 
minimum be removed.
