Yes, I think it's easier to achieve Platinum in this new scheme.
In this new scheme the Elite points which replace Elite sectors can be accrued easier if you fly short-medium hauls like KL to Manila/Taipei/Hong Kong. You'd get 3 point in business per sector, rather than 2 before.
But with the initial Platinum threshold lowered to 100 rather than 130 points/sectors, the mileage runs in Malaysia which still earn the same amount of points, have become more lucrative.
Must be said that for this year this will probably not help many people residing outside Malaysia as travel restrictions remain in place.
All in all, for now this doesn't seem dramatic for travelers.

I do wonder what they will do with status extension next year. I'd imagine MH has to give everyone another year extension as nobody will be able to fly enough otherwise this year.
