Most commonly, the **wider LP vote** is used for matters viewed as affecting all LP economics or governance, especially:

- **Conflicts of interest** where approval was moved from LPAC to **Majority in Interest of LPs**
- **Material amendments / major version upgrades** to the LPA
- Sometimes **broad waivers** that change LP rights in a meaningful way, rather than case-by-case administrative consents

Practical rule of thumb:

- **LPAC / Advisory Committee**: narrower oversight, situational judgments, administrative conflict review
- **Majority in Interest**: fund-wide conflicts, material governance changes, or anything that could look like a small subset binding everyone else

That shift appears intended to align conflict clearance with broader LP consent.
