What is it you don't like about it, out of interest?
Here’s the same type of junction: https://maps.app.goo.gl/tBvTQCj4UoCRxkfYA?g_st=ic
To turn left you don’t have an awkward entry angle onto the roundabout and therefore, do not have a reverse curve to negotiate to turn left.
With the M49 junction, with the sharp entry it has a reverse curve. Drivers turning left will often ignore the curve to take the straightest most natural path and end up on going wide toward the inside of the roundabout which isn’t good if they do not notice someone alongside them who is turning right. The design encourages entry path overlap. In other words it’s less numpty proof.
If you eliminate the reverse curve you won't achieve entry path deflection, which is important on a motorway slip road approach to a roundabout.
Surely the deflection should be approaching the entry rather than on the entry to the roundabout. There are plenty of examples of that from older designs: https://maps.app.goo.gl/vso6kUaNgvroS16V7?g_st=ic
Funnily enough, the first one is how I've always tried to build them in Cities: Skylines (and the game does NOT like it). It seemed intuitive; I didn't understand why.

Also the tendency to try and block the view of the roundabout on approach, so it is approached more tentatively
It even has an amusing pictogram of what I think of the Council highways bod who thought this would be a funny thing to do to drivers. Sequencing with traffic for best flow and fuel saving? Who's heard of it? That's something Londoners do isn't it, tantamount to dangerous driving! Put up some bloody great slabs in the way!
Oh, and if you hit a cyclist because you had 0.2 seconds to see them before you joined the roundabout, that's your fault and nobody else's, so there.

The cabinet report said the council would acquire the plots it needs but that because the CPO [Compulsory Purchase Order] process takes so long
and any objections from landowners require a public inquiry, the work would probably not start until
August next year [2024] at the earliest and be completed between August 2025 and February 2026.
