I believe some blockchain tracking analysts will "dust" addresses that were spent from (give them 546 sats), in the hope that lousy wallets will use the new 546-sat UTXO from the same address but spending to a different address and combining with *other* inputs with new addresses, thus allowing them to grow their datasets about fund ownership.

Indeed JoinMarket has a policy to ignore-by-default UTXOs that pay to an address it already spent from, precisely due to this (apparently common, since my JoinMarket maker got dusted a number of times already) practice.

I am personally unsure of how common this is but it seems likely that you can eliminate this effect by removing outputs of exactly 546 sats to reused addresses.
