Monero has now abandoned some of the legacy CryptoNote terminolgy it inherited.
As a result some new master tags were created. As an example
monero-wallet-cli has replaced
simplewallet in Monero v0.10.0 - Wolfram Warptangent.
My inclination would be to merge these tags as we already did with
monerod when it replaced
Are there any objections to such a tag merger on the basis of
simplewallet (or other legacy tags) still being used by other CryptoNote forks that are on topic on Stack Exchange
Currently most questions about other CryptoNote currencies (which are small in number) are comparison questions (with Monero) so I don't expect most legacy CryptoNote tags to be heavily used should they be preserved.
