Modifier state handling, group handling, etc. is still a private
implementation so even where the server supports individual keymaps. So it
remains to be seen if this approach is sufficient.
### Xwayland and XTEST
There are PoC implementations of using `libei` within Xwayland and
connecting it to a `libeis` context in the compositor (PoC with Weston).
This allows Xwayland to intercept XTEST events and route those through
the compositor instead.
### Short-lived applications
**libei** is not primarily designed for short-lived fire-and-forget-type
applications like `xdotool`. It provides context negotiation between the
server and the client - the latter must be able to adjust to limitations the
server imposes.
The current implemtation of the protocol however allows for a `libei` client
to send all requests in bulk and exit. Data is however processed in-sequence
by the `libeis` server so where the connection and device creation is
accepted by the server as-is, the requested events can be processed as-is.
