Liberty Tools Eclipse 23.0.6 can be installed on top of Eclipse 2023-06 (v4.24) works even though certain parts are non-functional (e.g. server.xml assist)

Perhaps we could/should try having a more restrictive versioning in either our feature.xml ? Like starting from this
https://github.com/OpenLiberty/open-liberty-tools/blob/integration/dev/com.ibm.ws.st.liberty.tools.base/feature.xml#L21C1-L25C15

   <requires>
      <import feature="com.ibm.xwt.dde.feature" version="1.0.600" match="greaterOrEqual"/>
      <import feature="com.ibm.ws.st.was.tools.common.core" version="1.0.2" match="greaterOrEqual"/>
      <import feature="com.ibm.ws.st.was.tools.common.ui" version="1.0.0" match="greaterOrEqual"/>
   </requires>

and using some of the other qualifiers here: https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Ffeature_manifest.html
(like 'equivalent' or 'compatible' )?

What would the Eclipse Marketplace experience be? Would this overall be a better experience?

Start with the requires block in com.ibm.ws.st.liberty.tools.base/feature.xml and read the linked Eclipse feature manifest documentation for the equivalent and compatible qualifiers. Investigate how stricter versioning would affect installation through Eclipse Marketplace, then define the supported-version behavior and verify that affected tools such as server.xml assist remain functional.
