Chance of Foreiner getting Entry Visa during Covid

[SingaporeDon]

ICA is not allowing foreigners to enter Singapore during the Covid circuit breaker
However they have a special application which if approved will grant entry pass and visitor's visa to foreigner children or spouses of Singapore citizens or PRs.

However they say such foreigner child/spouse will be allowed only in “extenuating reason”

Does anyone have first hand experience of what they mean by “extenuating reason”?

Presumably the child or spouse has no other available home/income/support or similar. Essentially someone who would be eligible for a LTVP anyways by the looks of it.
