This is not pulling the rug, it's just about removing support for 
dead-end technologies and pointing people to a better and all-in-all 
easier way of achieving the goals. Of course it requires some work, but 
longer term less so.

As usual, the 60 ESR cycle is coming to an end. There are not going to 
be any further (even) security fixes for the 60 series. The next upgrade 
step is to Thunderbird 68. With the 68.2 release, the 60.x series is EOL.

The numbers are small: Thunderbird 52 now has under 2.5% of users. But I 
don't think older versions is relevant to this discussion.
