We did not yet revisit this systematically.  Are there remaining 
observations with sledgehammer and other query operations via the 
canonical GUI panels?  Lets say in Isabelle/2f46999395e2 from today.

Oddly, people are still seen using 'find_theorems' etc. inlined into the 
source text.  That was an intermediate approach from several years ago. If 
it is still used today, what are the remaining resons for it?
