How to use OSC 52 clipboard for copy only?

[doums]

Problem

With terminals I use (wezterm/alacritty) the new osc52 clipboard feature works as expected for copy but not for paste operation.
For instance wezterm does not seem to allow reading the clipboard wez/wezterm/issues/2050

When I try to paste eg pressing p nvim become unresponsive, freeze during ~10seconds with the following message "Waiting for OSC 52 response from the terminal. Press Ctrl-C to interrupt…".
Finally, after this 10s timeouts or pressing ctrlC, the previously yanked text is pasted.

There is a way to set g.clipboard to enable osc52 for copy only, and keep whatever is nvim's default for paste?

I tried this but it's not working, I lose the osc52 feature

-- this is not working
vim.g.clipboard = {
  name = 'OSC 52',
  copy = {
    ['+'] = require('vim.ui.clipboard.osc52').copy('+'),
    ['*'] = require('vim.ui.clipboard.osc52').copy('*'),
  },
  paste = nil -- do not override it, use nvim's default
}

Steps to reproduce

1. start nvim with nvim --clean -u mini.lua

vim.o.clipboard = 'unnamedplus'

vim.g.clipboard = {
  name = 'OSC 52',
  copy = {
    ['+'] = require('vim.ui.clipboard.osc52').copy('+'),
    ['*'] = require('vim.ui.clipboard.osc52').copy('*'),
  },
  paste = {
    ['+'] = require('vim.ui.clipboard.osc52').paste('+'),
    ['*'] = require('vim.ui.clipboard.osc52').paste('*'),
  },
}

2. yank some text eg. y then paste p

Expected behavior

Should past the yanked text instant and do not freeze 10s with "Waiting for OSC 52 response from the terminal. Press Ctrl-C to interrupt..." message

Neovim version (nvim -v)

NVIM v0.10.0-dev-2682+g011585f35f RelWithDebInfo LuaJIT 2.1.1702233742

Vim (not Nvim) behaves the same?

I also encountered this problem with Windows Terminal.

The example in my recent issue might help you (by completing disabling pasting to + and *): #28611
It also resolves a related problem in Windows Terminal (and possibly others, I haven't checked) where yanking is slow.
