A permalink on the old code on ee-flow-big instance is

i.e. just the topic and with a fragment to scroll the post into view (and highlight with JS).
By 1.23wmf13 a permalink becomes
https://www.mediawiki.org/w/index.php?
title=Talk:Sandbox&
topic[postId]=050f56f284d4d0411a91842b2b774fd8&
workflow=050f142239ecc14b3c5090b11c2789df
#flow-post-050f56f284d4d0411a91842b2b774fd8
The topic[postId] isn't currently required, is it there for future-proofing? e.g. if we paginate topics or split posts.
