I'd argue it's way more complicated.
It's the boom years alright but not as you imagine them.
Back in the day anime had no financing at all, so they made OVAs. Today anime has all the financing this is why people are making 12 episode shows of EVERYTHING. Anime has x10 the money it had when OVAs where made. So there no need to make OVAs since you can just adapt one of the countless manga and LN into a full sized anime because all the manga and ln publishers already own the rights. It wasn't as integrated back then.
Let's take a look at FLCL that came out in Spring 2000.
Spring 2000 Season was :
Love Hina
Yugioh
Ayashi no Ceres
Gensoumaden Saiyuuki
NieA Under 7
Seikai no Senki
Sakura Taisen
Daa! Daa! Daa!
Boys Be...
Gate Keepers
Monster Farm: Legend e no Michi (Monster Rancher)
Transformers: Car Robots (Transformers: Robots in Disguise)
Hidamari no Ki
DokidokiDensetsu: Mahoujin Guruguru
Ginsoukikou Ordian
Fabre-sensei wa Meitantei
Time Bokan 2000: Kaitou Kiramekiman
So 17 brand new shows.
There was also some heavy hitters ongoing

In contract Spring 2025 had
49 brand new TV shows
13 Ongoing shows
6 ONAs of varying lenght some being full 24 episodes other 6 like Takopii

20 Anime Movies out of that 7 feature lenght and 4 recap movies
About 20+ various 1~5 minutes specials from Lycoris to Maomao
If you don't think it's the boom years I don't know what it is. There has never been more anime made in he history of anime on a seasonal basis. Not in terms of movies, not in therms of TV shows not in terms of "OVA" if they're the same as "ONA"
