Whether or not the CC-BY-SA requirement is less onerous rather depends on
what you're doing with the data.
I haven't looked at any OS licence conditions, but I imagine that if you
derive your data from OS maps, then you can probably combine your data
with another commercial map so long as you continue paying OS a licence
fee. On the other hand, data derived from OSM must be CC-BY-SA and
combining it with any commercial map would create a derived work which
would need to be CC-BY-SA - it's unlikely that the commercial map supplier
is going to allow this.
Also, I suspect that selling maps is a nice little earner for people such
as the land registry, so licensing them all as CC-BY-SA isn't in their
interest (as much as it may be in the tax payer's interest).
