Small "a" agile is defined by the dictionary and I'm wary that this is trying to redefine Agile as a synonym for "good".

In Good Strategy, Bad Strategy, Richard Rumelt says: "Strategy cannot be a useful concept if it is a synonym for success." The same thing applies to Agile. It's a strategy to achieve particular outcomes, arguably only one of which is "agility". Agile is only meaningful it is possible for it to be wrong or at least inferior to an alternate strategy. I don't think this happens with dictionaryism.

I wrote a bit about this here: What do you mean when you say “Agile”? | by Jason Yip | Medium

On the other side, "Agile" also doesn't mean what novices misunderstand it to mean. This leads to the cargo cult reinvention cycle I referenced in the post. If you don't understand or apply the strategy, you can't claim it doesn't work.

The answer to fanaticism is competence, not reinventing in circles.
