I believe shared_ptr is fine for what it was meant - a generally usable 
thread-safe smart pointer suitable for general use. It's true that for 
more specialized use cases one still needs to use custom solutions. 
That's the same as for iostreams, or for strtod() for that matter.

For me, the biggest drawback of std::shared_ptr is that it is 
multithread-safe. This means that it has to contain some thread 
synchronization, however lightweight it is. With modern hardware, I can 
have tens of threads running in full speed in parallel, if they each 
attempt to synchronize with each other, thousands of times per second, 
this is bound to have an impact. Compared with the expense of that, the 
amount of pointers (1 or 2), even the number of dynamic allocations (1 
or 2) pale in comparison (the dynamic allocations happen much more 
rarely then refcount updates).

So in our codebase there is a custom non-synchronized smart-pointer used 
for all the "data" classes (as opposed to "entity" classes). And you 
were right, it is based on intrusive refcounting in a super root class, 
just because all of the code is under our control anyway.

As it it not thread-safe, it requires extra care needs to be taken that 
no such pointer is ever accessed from multiple threads at the same time. 
For passing data to another thread deep copies are needed, etc.

The committee voted against of having a non-synchronized smartpointer 
class in the standard, in the fear this could easily cause subtle bugs 
which are hard to debug. And guess what? They were right! Over the years 
I have needed to fix several such bugs in my own code. I remember times 
when the bug just refused to express itself on my 4-core machine and I 
needed to find another 8-core machine and run the program for hours, to 
just trigger it.

So if I would sit on the committee, I would also vote against having 
such thing in the standard. C++ is already hard to use and full of 
gotchas even without it. And to be honest, considering it now should be 
classified as a slowish "safe easily usable class", there is really 
nothing wrong in adding an extra pointer or an extra allocation for 
making it even more easily usable.

TLDR; I agree with your criticism against std::shared_ptr, but on the 
other hand I believe its current design was and is the best one to 
standardize.
