Most of the removed options are many years old. In addition, they've all been removed in past iterations of Kubo. Some options were marked as removed in the config.md, but we still had a warning in the code to let users know they have been removed.
I think it's been long enough for all of this options, and enough Kubo iterations in order to alert the users. It is good to keep it in the config.md for now so that people can actually check. However, I think it's time to remove them from the code itself.
We've had a reliable and enabled by default TLS implementation since
0.4.23 (over a year ago) and turned off SECIO in September of last year.
We might as well remove support entirely in the next release and
encourage users to upgrade their networks.
Noise is faster, anyways.
