This question already has an answer here:
First off, I realize that a common reason that only a few target sites are listed for migration is because of overlap between different sites (i.e. the question may belong on multiple sites), and to prevent random questions being migrated to the Programmer SE.
However, given that questions asking for a recommended tool or library are considered off-topic for SO, and since there's the new Software Recommendations SE, wouldn't it make more sense to allow these otherwise off-topic questions on SO to be migrated to this new SR, rather than just closing them?
An example is the question Online static analysis tool. It was closed as off-topic by myself and others, but someone commented that it'd be well-suited for SR.
