/experimental UC receiving the same amount of requests than normal UC

[lemeurherve]

Follow-up issue from this #jenkins-infra chat thread: https://matrix.to/#/!JLUOInpEYmxJIYXlzs:matrix.org/$atGsZEcznI2e3gOYPTRMgKRhRBgdLO4_iV6MuR5Aaa0?via=g4v.dev&via=gitter.im&via=matrix.org

Looking at updates.jenkins.io access logs with JenkinsPluginManager as User Agent we noticed that the tool seems to request https://updates.jenkins.io/experimental/update-center.json each time it's used:

Is it expected?

plugin-installation-manager-tool/plugin-management-library/src/main/java/io/jenkins/tools/pluginmanager/impl/PluginManager.java

Line 869 in e88d9ab

experimentalUcJson = getJson(cfg.getJenkinsUcExperimental(), "experimental-update-center" + cacheSuffix);

This represents a non negligible part of the total traffic, can this be reviewed to be used only when experimental settings are set?
