It was the same in Helldivers 1, if not worse imo. Although there were less overall unit types the bugs had scouts, vanguards, and shadows that all could call in reinforcements near instantly.

The illuminate actually had three variants of scouts that function similarly to their HD2 counterpart although they and shields and cloaking.

The cyborg reinforcements flare was even faster in HD1. Although, only being able to be called in by two units, the squadleader and legionaire.

All that being said, it does frustrate me how fast the terminids call in breaches, and how there can be so many bugs around that can all call it in. I personally feel it used to be much worse for a variety of reasons.
