Release old versions of Source games for older computers and historical value

I am requesting re-releases of Half-Life 2, Episode One, Episode Two, Lost Coast, Half-Life 2 Deathmatch, Half-Life Source, Half-Life Deathmatch Source, Counter-Strike Source, Day of Defeat Source, Portal, and Team Fortress 2 that run on the versions of the Source engine the games ran on when they were first released. I am requesting this for the sake of players with older computers or hardware and for historical interest and value.

Here are the original source versions for each game for those interested:

Half-Life 2, Half-Life 2 Deathmatch, Half-Life Source, & Counter-Strike Source - 2004

Day of Defeat Source & Half-Life 2 Lost Coast - 2005 (I'm not really sure if it's called this, it may just be 2004 with HDR.)

Half-Life 2 Episode One & Half-Life Deathmatch Source - 2006 (Engine is found in tools section of the library as "Source SDK Base 2006".)

Half-Life 2 Episode Two, Portal, & Team Fortress 2 (Pre-Gold Rush Update) - 2007 (Engine is also found in tools section of the library as "Source SDK Base 2007".)

These old versions will be released as part of their updated versions. For example: purchasing Half-Life 2 will also give "Half-Life 2 (Source 2004)", which will be the same game, but running on Source 2004 as it was first released. Also purchasing Day of Defeat Source will give "Day of Defeat Source (Source 2005). As Team Fortress 2 is free-to-play, Team Fortress 2 (Source 2007) will also be free-to-play, and will appear in the user's library when Team Fortress 2 is installing, is installed, or is in the user's library.

Thank you for your understanding.
