Fluid tags at item 20000

[Memerto]

Hi! I'll reach item 20000 soon and I'd like to know more about the following item tags that are at the end of my items.xml.

I'm using TFS 0.3.6pl1 and protocol 8.6.

<item id="20001" name="water" />
    <item id="20002" name="blood" />
    <item id="20003" name="beer" />
    <item id="20004" name="slime" />
    <item id="20005" name="lemonade" />
    <item id="20006" name="milk" />
    <item id="20007" name="manafluid" />
    <item id="20010" name="lifefluid" />
    <item id="20011" name="oil" />
    <item id="20013" name="urine" />
    <item id="20014" name="coconut milk" />
    <item id="20015" name="wine" />
    <item id="20019" name="mud" />
    <item id="20021" name="fruit juice" />
    <item id="20026" name="lava" />
    <item id="20027" name="rum" />
    <item id="20028" name="swamp" />
    <item id="20035" name="tea" />

Are they important? Is it a problem if I delete, replace (with new items) or modify(for example, editing their id to 3000x+) them? Can I create new items after id 20035?

These items are not in the client, and I don't know if they have any use. Can somebody give me an explanation to bring some light on this?

If they aren't in the client you can use them, no clue why they are there.
I also dont' see a reason why you can't go over 20035.

And if they are important ... well, if they are in use on your server and you remove them they will get an "error" when looking at those items "report this to a GM" or something like that, but you won't debug.
