> My understanding is that this change is mostly a convenience change for native Windows developers, so that it becomes easier to run binaries after compilation (without installing?).

Even as non-Windows developer, I personally find it quite handy if all binaries end up in a single folder and are not scattered around in different places, unnecessarily still reflecting the in-tree source structure (resulting sometimes in long nested paths, as one can see in the scripted-diff).

I agree with this, and commit b6a39c81e85338bc82f3db924157a599aa7e25fa in this PR shows places where code is doing things like `strprintf("[" + comment + "]")` that get around compile time checking. It'd be great

Also added this to `29.x`, as if we are going to change this, it needs to happen along with the CMake switchover, and not be a new breaking change after that.

I also noticed using `getblock` sequentially on a large number of blocks was slow while checking for clusters of size > 2 in previously mined blocks see https://github.com/bitcoin/bitcoin/pull/30079#issuecomment-2113010122.

To investigate further, I conducted a benchmark on a VPS with specs:
- 8 vCPU Cores, 24 GB RAM, 1.2 TB SSD, 32 TB Traffic
- Running Ubuntu 22 with Bitcoin Core on latest master da10e0bab4a3e98868dd663af02c43b1dc8b7f4a

(https://github.com/bitcoin/bitcoin/pull/31179)
This PR is motivated by https://github.com/bitcoin/bitcoin/issues/30495#issuecomment-2444881418,
It adds a `reserve` member function to `UniValue` and applies it within the `getblock` RPC to pre-allocate memory, minimizing reallocations. This change provides a significant performance boost, particularly at verbosity levels 1 and 2.

@ismaelsadeeq nice find!

I wonder, could you also benchmark [batch requests](https://www.jsonrpc.org/specification#batch)? Sending a single request that contains `rpcthread` number of `getblock` requests, sequentially and multithreaded on the client side?

⚠️ sr-gi opened an issue: "`Wunused-member-function` in test each commit"
(https://github.com/bitcoin/bitcoin/issues/31180)
#31045 introduced `-werror` to test each commit, which makes things like `Wunused-member-function` an error now.

This feels pretty aggressive in the cases where some methods may be defined in isolation in commit A, and then used elsewhere in commit B (following A).

I think we can take this further and reserve for VOBJ types instead of just VARR.
The VOBJ uses both values and keys, so we can reserve both. We can count how many times we do `pushKV` and reserve that amount for both keys and values.
