The GB going beyond what the Bible says again? Well that's no surprise.
(1 Timothy 3:1) "This statement is trustworthy: If a man is reaching out to be an overseer, he is desirous of a fine work."
No guilting there, just encouragement. If you want to then great, but no punishment if you don't.
The Bible even says that some are better suited to some roles than others, not that everyone should be an elder.Besides, if the GB stuck to the qualifications listed in the 1Tim 3 and Titus 1 then more 'would' qualify.They have replaced the Bible qualifications with their own, mostly unwritten, largely BoE specific requirements.

I've forgotten others, but if you miss any single one of these don't expect to be an elder.
