I've always found "serverless" kinda "misleading" (technically).

Technically, SQLite is "embeddable InProcess".

And thus such a Process (similar to what was described for MySQL-
embedded above), could "very well be a DB-Server itself".

Your own Fossil-engine would be a good example for such a Server-App,
since it allows (very server-like):
- concurrent access of multiple Users via sockets...
- to access and manage data, which is stored in an SQLite-DB-File

I guess it boils down to "what amount of config- or coding-efforts"
are needed, to produce/compile a true ServerProcess with the help
of an embeddable "InProcess-Library".

E.g. my COM-wrapper for SQLite is implemented as a Dll as well
(and thus "embeddable InProcess") - but it allows with only two
lines of UserCode (just starting a COM-Lib-internal, threaded socket-
listener), to transform "any Host-Process" into an SQLite-Resultset-
read/write-supporting AppServer (which in many concurrent scenarios
outperforms MySQL and also the MS-SQLServer).

With the WAL-extension SQLite is usable in many different (concurrent)
Server-scenarios (and "Server-Processes") ...with a relative small
amount of "extra-code".

So in that sense, the word "serverless" kinda suggests that "special
usecase only" - which is not (only), what SQLite is used for in reality.
