Abhidhamma makes things really easy regarding interpretations of Dhamma

[Sabbe_Dhamma_Anatta]

Just recently, a thought occured to me that it is very fortunate for me to have some chances to get in touch with a little bit of Abhidhamma, making things really easy regarding interpretations of Dhamma readings. This thought formed after seeing the instances that even those very great minds of these (and recent) days who seemed not wanting to rely on abhidhamma usually ended up walking hazardously & laboriously on explanation about the attainments, on the verge of apparently contradicting the Buddha's teachings.

It is useful, yes.

Agree.
The knowledge of Abhidhamma is a great asset to a Dhamma teacher.
It even helps any person who likes to analyse the Dhamma in detail.
The drawback of Abhidhamma is you can confuse the teaching which has to be realised with experience mixed with intellectual realisation.
A person who relies only on Abhidhamma is in great danger than a person who rely upon only Sutta.
The best in my opinion is that you have to learn both.

Mahasi Sayadaw would agree with you on that point, imo. In the book "Atthakatha Saṅgāyana: Analysing (Auditing/investigating/Checking?)* the Saṅgāyana" [my translation from burmese book], which is a collection of his talks in the later part ? of Sixth Buddhist Council, regarding "Investigating/Analyzing" into Atthakathas, he said [my translation]:

• ... furthermore, as for Abhidhamma, it is purely the domain of panna. There is no mentioning of how to practice sila and samadhi. So, with pure Abhidhamma, it would not be possible to practice even sila and samadhi.
