I can understand that (i.e. why in place wont work), but the Q would be,
why one can't read in a document, add() or removeField() that document
and then updateDocument() that document.

I am not that familiar with Lucene, so my answer may be a bit off.
Search on the internet about log structured storage. There you will find
why rewriting an entry is better than updating an existing entry.
Leveldb/cassandra/bigTable use it. maybe search these terms as well.

so there are lots of Qs that are asked about wanting to modify a lucene
document (i.e. remove fields, add fields....) but are told that one needs
to reindex.
No one ever answers the technical Q of why this is, and I'm interested in
that. presumambly because documents aren't stored as documents or even in
any form that could be reassembled into a document, but I'm interested in
what the actual answer is.
thanks.
