Surely addressing and resolving non-commercially viable upgrades is one of the reasons for the BDUK programme?
Strictly, BDUK only targets the best two-thirds of the non-viable lines.
We've seen that a 100-line cabinet can be viable within BDUK, we don't really know whether a 100-line EO bundle would be.
However, to reach a 90% target, BDUK must cover either the set of EO lines or the set of lines that are > 1km from the cabinet, or a mix of the two. Both are reputedly about 10% of the line stock in the UK.
The best we can say is that surely *some* of them must be included.
Not that BDUK is going to help the significant number of Londoners stuck on EO lines.
Perhaps they'll get more cash from BDUK 2. I doubt it though, but who knows...
