I think there exists a nice balance between recognizing the facts that Raptor reliability is not good and that the launch pad was almost obliterated and the fact that SpaceX's iterative approach to this program means many of these issues will likely not be around in 5-10 flights.

SpaceX finally confirms they're certifying boosters to fly up to 20 times. This comes about a year since I originally reported this and even after a SpaceX official had told Aviation Week they were cutting it off at 15 flights...
To certify boosters for up to 20 flights, SpaceX will soon take B1060 out of the fleet for a deep study of reusability past 15 flights, it'll come back and it's expected to fly to 20 flights by next year. I wrote some words about it last month...

One thing that amazed me from finally seeing all 33 engines igniting on Super Heavy is the effect of the engine plumes recontacting several meters away in some sort of Mach diamond kind of thing. Definitely a very interesting effect of the interaction between Raptor exhausts.

Super stoked to have captured Booster 9 and her Raptor engines in their glory this morning - the was the first time all 33 were successfully ignited with continuous burn through first stage flight.
