Does using attribute-aware remap makes meshopt_simplify equiavlent to meshopt_simplifyWithAttributes?

I noticed that meshopt_simplifyWithAttributes converges to a suboptimal index count while using attribute-unaware API performed as expected. Naturally I tried replacing meshopt_simplifyWithAttributes with meshopt_simplify for sparse LODs. This didn't do the trick.
Changing remap method however from meshopt_generateVertexRemapMulti to meshopt_generateVertexRemap did great - non-sparse LODs didn't change and sparse ones were simplified as expected

Is there a neat way of fixing this?

Nevermind, discovered Permissive mode. Apparently, LODs are very nuanced
