I think
duplication is a major issue with new extensions.
There are too many overlapping/redundant strings, plus singular/plural and foreign languages variations.
Examples of alternatives to .realestate:
.PROPERTY .PROPERTIES .REALTY .APARTMENTS .HOMES .CONDOS .VILLAS .MORTGAGE .RENT .RENTALS .HOUSE
Plus foreign variants: .MAISON .HAUS .IMMO .IMMOBILIEN .CASA

Then you have stuff like .pics .pictures .picture
.photo .photos .photography
I mean, come on
For a domain holder this is problematic. You kinda feel 'compelled' to secure the variants of your domain to cover bases. Not just existing variants but future ones as well. That creates overhead and uncertainty.
On the other hand,
aliasing would have been an option to alleviate the issue.
This is what Cira does for .ca domains. If your register a name with (or without) accents you don't have to worry about the variations, they are reserved for you. If you own telephone.ca someone else cannot register téléphone.ca. But you can if you want it. Peace of mind.

Likewise, if you could register .photo and automatically have rights on the .photos .photography counterparts this would be nice. Even better if all the names were automatically registered and resolving across extensions. Just a thought.
We don't need hundreds of arbitrary strings. Opening the floodgates like Icann did is bad and hurts the industry as a whole, including the industry players.
I think new extensions should be introduced sparingly, on a case by case basis, after careful evaluation of their viability. What they did is damaging and destabilizing to the domain ecosystem.
Keep in mind the real goal of all of this was to create new revenue streams for the registrars and the registries.
