T follicular helper cell logical definition using obsolete term

[anitacaron]

I was browsing the CL and found out there's an obsolete GO term dangling there. Not surprisingly, this is already an old issue. It might be an easy fix, so I'm bringing it to your attention again.

@dosumis opened this ticket last year about obsolete non-CL terms found in CL by reference check.

I spotted another one by chance, and wonder if there are others:

'T follicular helper cell' Equivalent To 'CD4-positive helper T cell' and ('capable of' some GO_0051024)

Where GO_0051024 is obsolete. In Protege it shows as strikethrough, but in OLS it doesn't, and in Ontobee it's only slightly more evident.

In this case, the obsolete GO term has a replaced_by. Is there a way to trigger the replacement automatically, or at least to flag all instances of external classes that have OBO-compliant obsolete tags? Possibly run as a check with warnings (not errors) before each release?

Tentatively assigning to @matentzn , though I see that this ticket is in the Icebox, and it's certainly not too urgent.

Thanks!

Or just manually replace GO:0051024 with GO:0002639, which would be correct biologically.
