The 3MB size is the size of an empty DB spatialite .
A DB emty is 3MB size .
A DBspatialite with 1 single dataset of 10MB is
3MB +10MB = 13MB.
A DBspatialite with 3 dataset everyone of 10MB is
3MB + 10MB +10MB + 10MB = 33MB.
Also, AFAIK the goal of Luigi is storing in the spatialite the SLD
finalized to rendering the same dataset stored in the spatialite,
not to store SLD for general usage.

Andrea.

Saving style as spatialite files would probably cause a significant
file size overhead - don't all spatialite files take at least 3MB for
the SRS tables?

Hi,
I'm developing a new feature to save SLD and ui in Spatialite
provider in the same way this function is available for postgres.
this function developed for Faunalia is funded by ARPA Piemonte
fork is available at:
https://github.com/luipir/QGIS/tree/spatialite-savestyle
and actual modification are localized in this
commit: f058bea1fe51116b8231eb5c1ca4faee485c38b2
there are some question about how to develop it and are related
how to manage XML in a sqlite/spatialite table.
this code derive by the postgres provider code where QML and UI
xmls are recorded in a XML column. XML is a postgres type. This
type is not available in SQlite but it's available in SL 4.1>
(called XmlBlob [1])
In this preliminary commit XML is saved in a text column, but
saving XML as a blog (blob type in sqlite or XmlBlob in SL) have
the advantage to avoid all encoding problems.
so the question is... sqlite blob or spatialite xmlbob?
Blob type can't allow XML parsing using SQL queries
XmlBlob allows this (using libxml2)
Blob type is sqlite native type
XmlBlob can be used only with SL 4.1>
My preference is to use native data type Blob. What's you opinion
about blob/ xmlblob or whatever
