Naturalisation eligibility after ILR - Spouse route

[aa2016]

Hi everyone,
I would appreciate some advice regarding my husband's immigration status suitable for naturalisation application.
My husband has completed 5 years in the UK as a Skilled Worker dependant and is now eligible to apply for ILR. I currently hold ILR and have already applied for naturalisation.
Would it be better for him to apply for ILR now, or should he wait until I become a British citizen?
If he applies for ILR now and I become a British citizen before he applies for naturalisation, would he be eligible to apply for naturalisation immediately after receiving ILR as the spouse of a British citizen, or would he still need to wait 12 months after being granted ILR?
Alternatively, if he waits and applies for ILR only after I become a British citizen, would that make any difference to when he can apply for naturalisation?
Has anyone been in a similar situation or knows how the Home Office applies the rules in this scenario?
Thank you in advance for your help.

If he is eligible for ILR now why not apply now. There's no reason to wait until you become BC. Naturalisation is separate from immigration and has it's own law and rule. HO applies the rules.

Can apply immediately if he holds ILR on the date you become BC (at the ceremony).
Alternatively, if he waits and applies for ILR only after I become a British citizen, would that make any difference to when he can apply for naturalisation?
Why wait if he is eligible now? He needs ILR for naturalisation anyway.
Has anyone been in a similar situation or knows how the Home Office applies the rules in this scenario?
This is not an odd situation, HO applies the rules, as I pointed out.
Thank you in advance for your help.
