What's your estimate of the lead time required to kick the can,
if-and-when it becomes necessary?

The other time-series I've seen all plot an average block size.  That's
misleading, because there's a distribution of block sizes.  If you bin
by retarget interval and plot every single block, you get this

The max block size has clearly been in play for 8 months already.
