Is the time it takes to spin up a database really a primary concern for anyone but a hobbyist? Hopefully one would take far more than 10 seconds to address the actual concerns of database work: backups, replication, upgrade procedures, access control, settings tuning, required extensions, etc.

If anything, companies are drowning in a proliferation of siloed datastores and most are highly motivated to fix that situation; the exact opposite concern of "quickly spin up a new database".

Feature or liability depending on the market segment. To a ton of enterprise customers this is a nightmare.
