why was slf4j-api added as a dependency?

[zoff99]

i read: #997 (comment)
and: 32082c0
and: 89dbda1

but i can not see any reason this was done.

here it says "Read the Changelog", but there is nothing about slf4j-api in the changelog.
why was this added? can you link to documentation about the decision or some code in sqlite that requires it?

why was it not possible to make this optional?

it was added because it's used in almost any library, and it lets the application control logging. You can check #802
