I've actually tried a couple of workarounds for this over the years.
1) defeated computer
- cost: lose 1 player slot, new units can't be created
2) shared vision computer
- cost: burrowed unit reveals an area at all times
3) parasite'd units
- cost: need a computer to cast parasite, players always see the burrowed unit
4) player-owned burrowed unit
- cost: always see burrowed unit, lurkers will attack
5) plagued/ensnared units
- cost: you need a system to constantly create, ensnare, burrow, and replenish the burrowed units
6) vision update trick
- cost: you need to know the exact number of units every 300th frame; only some indexes work, and the system won't work if a unit is blinded in the game
- note: I've attached a map for this one
7) hallucinated units
- cost: may not work anymore? have to replenish the unit before it dies
Having a defeated computer to reveal the burrowed units is by far the easiest solution, so I'd recommend it. If you have a set number of units, option 6 is interesting to play around with. I can explain it in detail if you'd like.
In response to your previous post, I have no idea which flag is used to reveal an invisible unit to all players, but I remember something similar happening with hallucinated cloaked units. Are hallucinated burrowed units still visible to all players? I honestly can't remember.
