Generating the filename from name and file-ext for blocks with side-effects

[Aitenate <aitenate@outlook.com>]

With ~:results file~, the absence of ~:file~ will cause the filename to
be constructed from the block name and ~:file-ext~, if they are both
present. To achieve that with ~:results file link~, I could only come up
with

~:var outFile=(alist-get :file (nth 2 (org-babel-get-src-block-info
't)))~

Have I missed something obvious? Is there a better way to do this?

If there isn't, would it be acceptable to add something like
`org-babel-get-src-block-param-value' or maybe more specific like
`org-babel-get-src-block-results-file-name'?
