The page id is in the url for a reason - it keeps the state of your page.
If the page is stateless then there is no pageId and no redirect. So both
bots are happy and performance is better.
But Wicket's power is in its state management. If you render a stateful
page without the pageId then the state is gone if the user refreshes the
page with F5/Ctrl+r.

You have the following options:
1) use ONE_PASS_RENDER strategy and see whether this leads to any bugs.
Usually changing the strategy should be transparent but better test well
before rolling out
2) refactor your app to be stateless. Since 7.4.0 even the Ajax components
and behaviors could be stateless, so it is not impossible
3) Use HTTP2 enabled web server. This reduces the latency by other means
