Breadcrumb trail

Hi all.

I see that w3 and WCAG give examples of breadcrumb trails whereby they are all links...even the last one..which typically I am used to seeing as plain text...with aria-current being used on the <li> element to convey the cuurrent page....but lots of examples use the page they are on as a link, too.

Personally I think it doesn't matter whether it's a link or plain text..although I am slightly swaying towards it's OK being a link for users that may want to refresh the page I guess. I would just like your opinion if possible - please! Thank you.
