Blocks should carry an author label, without doubt. Navigating and inserting is cumbersome enough without having the added confusion of blocks with identical names. Lacking clear identifiers it’ll be way too easy to turn the inserter into an absolute shitshow. In my own experience I try to avoid third party blocks unless absolutely necessary an example of why being a recently installed plugin which I used for a quick fix to get a specific gallery feature. It only contained 3 blocks, upon subsequent updates this has now ballooned to 38, yes thirty eight along with an obscene amount of options which slowed the editor too a crawl. I decided to bite the bullet and implemented the feature using ACF so I could again dump the third party block. Still, there are notable examples of excellent blocks such as https://wordpress.org/plugins/accordion-blocks/ simple, clear, un-opinionated styling and it does exactly what is says on the tin.
