I don't think any plugin depends on that. And even if there exists
such a plugin, the usability benefit greatly outweighs the cost of a
broken plugin which made this fragile assumption instead of using the
'[ and '] registers. Good engineering weighs cost vs. benefit: the
cost here is hypothetical and small, and the benefit is that a
long-standing usability problem in Vim will be fixed.
