For me personally SharedPtr is very rarely needed as it encourages building difficult to untangle ownership hierarchies. I did use a lot of Shared Ptr in the past when creating a node.js like library in C++ but breaking the ref cycles everywhere was needed has always been a pain.
That's why I am currently against its use, unless there is a very special case.
Regarding UniquePtr<T> I used to have one but I later on decided to remove it.
However, that being said the library is lean enough so that you can still use it with smart pointers provided by any other library (including the standard one) if that's your preference.

Is the point of having a kitchen-sink library like this not that you dont have to reach for a 3rdparty library for things that you need 'all the time'?
Certainly, not everyone needs it.
...but, not everyone needs threads either. Not everyone needs an http server; and yet, if you have an application framework that provides them, when you do need them, it saves you reaching for yet-another-dependency.
Was that not the point from the beginning?
unique_ptr is a fundamental primitive for many, as you see from some other frameworks (1), and implementation is not always either a) trivial, or b) as simple as 'just use std::unique_ptr'.
This does seem like a very opinionated decision with reasonably unclear justification; perfectly fair, you're certainly not beholden to anyone to implement features just because they want you to, but I think it's difficult to argue there's not concrete use for something like this, in a way that aligns with the project principals.
I would go so far as to argue that:
> Do not allocate many tiny objects with their own lifetime (and *probably unclear or shared ownership*)
