It's not even really a question of attention so much as maintenance. Fixed up front costs are easy to handle as capital that can go into their rate cases, but more so power equipment lifetime is measured in decades and the discharge lifecycles of available battery technology is already not great for an installation expected to go to near full discharge on a regular basis.

If the planned usage is only a 10% semi-daily scenario for stability support that may result in 5-10 years longer lifetimes versus daily discharges for capacity shifting.
