GWR▸ have introduced 'Long Weekender' return fares from Paddington to the following stations. Out anytime on a Friday or Saturday, return on Monday (Railcard prices in brackets):
Swindon/Chippenham £69 (£45.50)
Bath/Bristol
TM‡/Bristol Parkway £79 (£52.10)
Newport/Cardiff £99 (£65.30)
With there being no time restrictions on these tickets they could be used instead of an Anytime Single during the Friday evening and Monday morning peaks. Quite a saving.
And anyone wanting a long weekend to destinations beyond those above can potentially make quite a saving with split tickets.

For people with who live out west, but stay in London during the week, these tickets could be useful to pop home for the weekend.

... but please bear in mind as you read my comments I'm looking at the technicalities of the new offer and what it provides, nd not taking a "pop" at any particular groups who happen to benefit from it. In many ways, it does seem to be another layer / option added rather than the holy grail of simplification
